When robots take all of the jobs, one result will be that some services previously only available at a high price will become much more affordable. So, instead of taking jobs, they will be improving our lifestyle.
They’ll probably take a few jobs, too, a major technological change to society like that is bound to be a bit wrenching. Of course, robocars are going to eliminate a lot of jobs for truck drivers and cab drivers. On the other hand, that means that shipping costs will be lowered which is bound to be good for the economy, and cab drivers will no longer be able to defraud people.
They might still be able to converse, though, which will be interesting. You won’t have to tip your robot bartenders and waitresses. But, there’s a couple of other jobs I’m thinking of. Robot massage parlors will boom. No, I’m not talking about sex dolls. Seriously. A robot masseur doesn’t need to make a living wage, and they can work long hours and apply just the right pressure and it will be cheap enough everybody can go get one at the end of a hard day’s work because, hey, why not, we’ve earned it.
Another one, which depends on a certain amount of near sentience, being able to respond to questions and statements with understanding, is psychology. Who goes to psychologists today? Not many. It’s expensive, and a lot of people don’t want to pour out their troubles to a stranger, no matter how committed they are to doctor-patient privilege. A robot with a nice soothing voice and a literally encyclopedic knowledge of human emotions and ailments and a completely non-judgemental attitude, on account of not actually being human, might just smooth right over that problem.
Those are a couple of jobs where I think they will have a positive impact, and expand the field rather than take jobs. I’m sure there will be others.
